I'm not sure if this is relevant to the freezing of the server because its capacitor was replace with a new one before I install CentOS.
Do I have to worry on those logs? 2 days had past after this error appear. So far I haven't see it again but I want to know if this could be the cause of the server hangup? I think server should not be hang because this error is only about network. Am I correct? |
